LUBRICIOUS EXTRUDED MEDICAL TUBING |
摘要 |
A medical tube having improved lubricity is disclosed. The medical tube is produced by extruding a polymer material blended with a lubricity enhancing additive through a resilient die. The polymer material can be medical-grade high-density polyethylene, and the lubricity enhancing additive can be a silicone-based or alloy-based material. The medical tube can include one or more internal elongated protuberances so as to reduce the internal surface area of the medical tube available to generate friction on a guide wire inserted or withdrawn through the medical tube. |

1. A lubricious medical tube formed from a blended material including:
organic polymer resin; and a lubricity enhancing additive including siloxane is blended with the organic polymer resin to form a blended material, the lubricity enhancing additive being blended with the organic polymer resin at a concentration of less than 10%, wherein the blended material is disposed in a substantially tubular configuration bounded by an inner surface and an outer surface encompassing the inner surface. |
